Specification of Letters Patent.

Patented June 1, 1915.

Application filed June 18, 1914. Serial No. 845,841.

To all whom it may concern:

Be it known that I, KARL SENN, a citizen of the United States, residingat Alameda, in the county of Alameda and State of California, haveinvented new and useful Improvements in Combined Batea, Jig, and PanMotion Concentrators, of which the following is a specification. i VThis invention relates to concentrating apparatus. V

It is an object of this invention to pro vide means for subjecting orepulp to a wave-producing motion, the waves acting concurrently with acurrent flow to carry off gangue, and to separate the values, both freeand combined, from the pulp.

A particular object of the invention is to provide an apparatus forhandling finely comminuted pulp or slimes.

The invention consists of the parts and the construction and combinationof parts as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which 1 Figure 1 is planview. Fig. 2 is a side elevation partly in section. Fig. 3 is a detailsectional view. Fig.4 is a detail section of the supporting. column.

2 is a shallow, circular, concave pan erected upon a spider frame 3attached to parallel beams 4. The beams 4 are supported upon uprightspring legs 5 secured in pairs upon opposite sides of a carrier frame 6.The carrier is suspended for transverse or's'ide shakeby suspending arms7 connected at their upper ends to standards 8. Journaled in thestandards, at one side of the carrier 6,

is a shaft 9, carrying eccentrics 1010 with connecting rols 11 ointed tothe carrier 6 for reciprocating the latter sidewise. The shaft 9 alsocarries an eccentric 12, connected by a link 13 to a rock lever 14: on arockshaft 15, journaled upon the carrier 6. The

rock-shaft is connected by a rocker-arm or arms 16 to the pan beams 4and reciprocates this perpendicularly to the carrier motion. The pan is,therefore, moved orbitally at every point by the combined fore and aftand side shakes.

' Mounted above the center of the pan 2 is a feed head-17, having avalve plate 18, between the circumferential edge of which and theannular lip 19 of the head is formed a mouth 20. Below the head 17 and-cen trally of the pan 2, i-sa preliminary or ini tial bowl or batea 21,the ridge 22 of which pan and below the ridge of the pan 2. The

height of the aperture may be varied by raising or lowering the batea21. The center of the batea is deepened, with a side wall 26 of greaterangle than the angle of the outer slope, and is provided with aremovable screen bottom 27, of desired character, upon which isdeposited a mobile mass, as a quantity of rounded bodies or steel balls28.

At the bottom of the pan 2 is an open mouth cone 29, to the lower andsmall end of which is connected a discharge pipe 30. Connected to thecone, by a pipe 31, is a pump 32, the piston of which is connected to aconvenient part of the carrier as shown in Fig. 2 so that the latter isused to drive the pump piston, the cylinder of which moves with the panrelative to the carrier 6.

vSuitable check-valves and cocks are provided, as at 33 and 3a, tocontrol the fluid flow.

The operation and function of the apparatus are as follows Power'fromany suit able source being applied to the shaft 9, the carrier isreciprocated laterally carrying with it the pan. This latter'isreciprocated at right angles to the carrier motion and, therefore, hasan orbital gyration in a horizontal plane. Pulp is fed to the head 17and discharged by the annular mouth 20 thereof onto the batea 21, whichis filled with water which covers the mouth. The pulp issuing from themouth 20 is immediately greatly diluted by the Water in the batea andthe heaviest values gravitate at onceto the central bottom portion andenter the interstices in the mobile mass or between the balls 28, thelargest articles being retained upon the screen 2% and the smallerpassing through. Interposed between the screen 27 and the mouth of thecone 29 is a second screen 35 supporting a mobile mass, as balls 36. Theconcentrates accruing upon the screens 27-35 are constantly subjected,in addition to the agitating motion of the pan, to a hydraulic jiggingaction derived from the pulsations of water from the pump 32 through thepipe 31. This jigging prevents the concentrates from packing as wellalso as the mobile mass of balls on each screen, but the additionaleffect of the hydraulic jigging is to thinthe accumulation and allow theheavy concentrates to find quick egress through the screens to the conebottom. Meanwhile, the fine slime is kept in suspension and is washedoutward from below the batea 21 through the mouth 25.

,The quantity of water injected into the cone incline of the pan inopposition to thecoun- 'ter-current issuing from the mouth 25. To

add further clear water to the pulp and to control the outwardcounter-current at the mouth25 without varying the pulsation from thepump, there is provided, below the batea, a circular pipe 37perforatedto spray jets of water downwardly. Thls addquantity .fiowsoutwardly through the mouth 25 and the force of the counter-current actsto throw gangue outward while still permitting the concentrate togravitate toward the screen 35. j I have devised, constructed andsuccessfully utilized an apparatus, as descrlbed, by which pulp isconcentrated by gravltat on, while subjected to agitation on acollecting surface, is washed by counter-currents, and

agitated by hydraulic jigging.

' Having thus described my invention, what I claim and desire to secureby Letters Patent'is j 1. The combination in a concentrator, of

a concave pan with a central discharge,

means for feeding pulp at the center of the pan, a screen in the pandischarge and supporting a mobile mass, the partlcles of which are toolarge to pass through the screen, meansfor gyrating the pan to agitatesaid mass and the ore solids concentrated, the

concentrate gravitating toward and through 7 the screen and the ganguebeingwashed outwardly by the wave action and water flow, means, forhydraulically jigging the concen trate and the mobile mass at thescreen, and

' a v preliminary separator superposed above the pan discharge and'intowhich the feedmg means discharges pulp, the rim of the separator beingadjustable relative to the surface of the pan to form an annular mouth,through which a counter-current,

derived from. the jigging means, runs outward.

The combination in a concentrator, of a concave pan with a centraldischarge, means for feeding pulp at the center of the pan, a screen .inthe pan discharge and supportlng a mobile mass, the particles of whichare too V the pulp and for varyingthe strength of the large to passthrough the screen, means for gyrating the pan to agitate said mass andthe ore solidsconcentrated, the concentrate gravitatin'g toward andthrough the screen and the gangue being washed outwardly by the waveaction and water flow, means for screen in the pan dischargeandsupporting a mobile mass, the particles of which are too large topass through thescreen, means for gyrating the pan to agitate said massand the ore solids concentrated, the concentrate gravitating toward andthrough the screen and the gangue being washed outwardly by the waveaction and gwater flow, means for hydraulically jigging the concentrateand the mobile mass at thescreen, a preliminary separator superposedabove'th'e "pan dis-.
